TLDR
Novel observations have provided an improved understanding of the contribution of tissue-specific factors and associated damage, T and B lymphocytes, as well as innate immune cell subsets and their corresponding abnormalities.

Sex Hormones in Acquired Immunity and Autoimmune Disease.

TL;DR: The role of sex hormones particularly estrogen, in the adaptive immune response, in health, and autoimmune disease with an emphasis on systemic lupus erythematosus is focused on.
Journal ArticleDOI

Autoimmunity and organ damage in systemic lupus erythematosus

TL;DR: Tsokos reviews how the genetic, epigenetic and microbial environments influence innate and adaptive immune cells to drive immunopathology and organ damage in systemic lupus erythematosus.

Th17 Cells and the IL-23/IL-17 Axis in the Pathogenesis of Periodontitis and Immune-Mediated Inflammatory Diseases

TL;DR: A review of the current knowledge about the differentiation of Th17 cells and the role of the IL-17/IL-23 axis in the pathogenesis of IMIDs aims to review the association of these IMIDs with periodontitis and briefly discusses the therapeutic potential of agents that modulate the IL

Regulatory T cells in the treatment of disease

TL;DR: The current progress in modulating Treg cells in autoimmune disorders, transplantation and cancer is described to promote antitumour immunity and regression.

Aberrant T Cell Signaling and Subsets in Systemic Lupus Erythematosus.

TL;DR: A better understanding of the molecular defects including signaling events and gene regulation underlying the dysfunctional T cells in SLE is necessary to pave the path for better management, therapy, and perhaps prevention of this complex disease.

Identification of Tim4 as a phosphatidylserine receptor.

TL;DR: Results indicate that Tim4 and Tim1 are phosphatidylserine receptors for the engulfment of apoptotic cells, and may also be involved in intercellular signalling in which exosomes are involved.

CD69 acts downstream of interferon-alpha/beta to inhibit S1P1 and lymphocyte egress from lymphoid organs.

TL;DR: Treatment with the IFN-α/β inducer polyinosine polycytidylic acid inhibited egress by a mechanism that was partly lymphocyte-intrinsic, and observations indicate that CD69 forms a complex with and negatively regulates S1P1 and that it functions downstream ofIFN- α/β, and possibly other activating stimuli, to promote lymphocyte retention in lymphoid organs.

Toll-like receptor 7 and TLR9 dictate autoantibody specificity and have opposing inflammatory and regulatory roles in a murine model of lupus.

TL;DR: It is reported that lupus-prone mice deficient in TLR7, a receptor for ssRNA, failed to generate Abs to RNA-containing antigens (Ags) such as Smith (Sm) Ag and TLR9, and this results have important implications for TLR-directed therapy of autoimmune disease.

Type I Interferons Keep Activated T Cells Alive

TL;DR: Since IFN-α/β are very efficiently generated in response to viral and bacterial infections, these molecules may be among the signals that the immune system uses to prevent activated T cell death during infections.
